Okay, so... Turns out it was not that hard... :)
With two helper functions I could rewrite the suggest function quite nicely:
(defun asug-count-words (expansion)
(length (split-string expansion " " t)))
(defun asug-get-previous-words (n)
(let ((end (point))
words)
(save-excursion
(backward-word n)
(replace-regexp-in-string
"[\n\r]" " "
(buffer-substring-no-properties (point) end)))))
(defun absug-maybe-suggest ()
"Suggest an abbrev to the user based on the word(s) before point."
(let ((expansions (absug-get-active-abbrev-expansions))
words found expansion word-count)
(while (and expansions
(not found))
(setq expansion (pop expansions))
(when expansion
(setq word-count (asug-count-words (car expansion))
words (asug-get-previous-words word-count))
(when (and (> word-count 0)
(string= words (car expansion)))
(setq found t)
(message "You can write `%s' using the abbrev `%s'."
(car expansion) (cdr expansion)))))))
It works for abbrevs that has an expansion with multiple words and
it also works across lines.
Now I will clean this up a bit and checkdoc it...
